Do you have any idea of age and origin?
I suppose they were made in a two piece gypsum mould with liquid casting porcelain clay. If enough clay has been deposited on the inside of the mold the liquid rest is poured out again, leaving a hollow inside, After some hours the leather hard clay is removed from the mould and the perforation can be made. When the beads are completely dry they get a first (biscuit) burn in the furnace. After firing the biscuit bead can be colored and get an overlay of transparent glaze and after drying again they get a second burn in the furnace.
